Question

Select the wrong statement about interstitial compounds from the given options:

• A. These compounds are not inert in nature
• B. These compounds have high melting points
• C. The hardness of these compounds are compared with diamonds
• D. The conductivity of these compounds are sililar to their parent metals

Answer 1

The correct option is A

These compounds are not inert in nature

Explanation for the correct answer:-

Option (A) These compounds are not inert in nature

• In the interstitial spaces the impurity ions are present such as Carbon, Nitrogen, Hydrogen, Boron.
• This makes the interstitial compounds chemically inert, that is they do not easily react and they also help in retaining the metallic conductivity.
• These compound has similar chemical properties(reactivity) to the ones of their parent atom, but they differ in their physical properties.

Therefore, the wrong statement is option (A) These compounds are not inert in nature
